How to build a circular LCD clock, step 1: buy a circular LCD that looks like a clock.
I'm not kidding, that's the extent of the build. They simply connect that display to a computer over HDMI. The only hacking here is browser-based JS for clock animations.

You don't need a browser to display graphics. And you don't need to be a programming whiz either. I'm sure Claude could write some python to render these clock faces.
Driving HDMI is way harder then you would guess; extremely fast timing to hit. A naive framebuffer alone won't fit in RAM, whilst not strictly needed it would make it a hard challenge.

I found that the surf browser was efficient enough to run fine on my Raspberry Pi Zero W. YMMV with animations and such, but it's much better than any chromium alternative in my experience.

I know this isn't exactly a serious product and more of a gadget/gimmick but man we are off by a factor of like 3-4 here :D

Nice implementation though!

Why do they need to be ...white :)
Oh i see the cables now and cant unsee them.
I guess next step is to 3D print a back case mount that encloses the RPi and plugs into a wall socket for power.
